Great, great build in 0.91. Stability, speed, graphics all much improved, well done!
It would be nice to reorder queues, both construction and spell research. The intuitive thing would be to pick up a queue medallion and move it in front of or after another medallion in the queue. I found myself wanting to change the order of builds as new lands were unveiled, and right now, the only way to do that is to cancel and reorder, but you lose your investment. That may be by game design, but if it's not, make it easy on us.
